Description

[Detailed Description of the Invention] [Objective of the Invention] (Field of Industrial Application) The present invention relates to a knitted fabric lowering guide device for a sock knitting machine that guides the knitted fabric downward without slack in the sock knitting machine.

(Prior Art) Conventionally, a knitted fabric lowering guide device of this type of sock knitting machine has been constructed as shown in FIGS. 4 to 6 (Japanese Utility Model Publication No. 10130/1983).

That is, in FIGS. 4 to 6, a knitting fabric guide cylinder 2 is fitted inside a knitting machine cylinder 1 in a sock knitting machine, and an upper opening 2a of this knitting fabric guide cylinder 2 is It is formed in a wrapper shape, and a notch 3 is formed in a part of the upper opening 2a. Further, a through hole 4 is perpendicularly bored in the upper opening 2a beside the notch 3,
An L-shaped support shaft 5 is rotatably mounted in the through hole 4, and one end 6a of a leaf-shaped fabric lowering guide member 6 is attached to the inner end of the support shaft 5. It is pivoted for free movement. Furthermore, a loop-shaped suction pipe 7 is connected directly below the knitted fabric guide cylinder 2 with a slight gap, and a fabric storage tank 8 is connected to the terminal end 7a of the suction pipe 7. It is provided to store products such as knitted socks. Furthermore, the lower part 8a of this fabric storage tank 8
A suction fan 9 is connected through a connecting pipe 10, and a communicating pipe 12 equipped with an on-off valve 11 is connected between a part of the suction fan 9 and the straight section 7b of the suction pipe 7. connected.

Therefore, when the knitted fabric lowering guide device of the sock knitting machine described above guides the sock fabric W hanging down from the knitting machine cylinder during the sock knitting process to the upper opening 2a of the knitted fabric guide cylinder 2, At the same time, the fabric lowering guide member 6 swings to pull the hanging sock fabric W downward. Further, the sock fabric W guided into the knitted fabric guide cylinder 2 is pulled downward into the suction pipe 7 by the suction force of the suction fan 9 that is being driven in advance. The sock fabric W inside is stored in the fabric storage tank 8. However, the above-mentioned sock fabric W is stored in this fabric storage tank 8.
When the tank becomes full, the opening/closing valve 11 is opened and air is temporarily blown up by the suction fan 9 from the lower part 8a of the fabric storage tank 8 through the communication pipe 12 and the communication pipe 10. The above-mentioned sock fabric W stored in the fabric storage tank 8
is taken out to the outside.

(Problem to be solved by the invention) However, although the above-mentioned fabric lowering guide device of the sock knitting machine is theoretically effective, the effect of lowering the fabric depends on the quality of the yarn, the thickness of the yarn, etc. or cause
This is done by welding or soldering the connecting part of the fabric lowering guide member 6 to avoid burrs that may cause wrinkles due to uneven lowering of the knitted fabric, which makes it difficult to improve the quality of socks. Poor finishing may cause the knitted fabric to pull, and
When replacing the fabric lowering guide member 6 according to the knitting conditions of socks, the fabric guide cylinder 2 must be removed from the knitting machine cylinder 1 of the sock knitting machine, which is cumbersome to handle. In addition, since the entire apparatus is temporarily stopped, there are drawbacks such as a decrease in production efficiency.

The present invention was developed in view of the above-mentioned circumstances, and it prevents the strength of the knitted fabric lowering effect from varying depending on the yarn quality, thread thickness, etc., and prevents the occurrence of uneven knitted fabric lowering and wrinkles. In addition to improving the quality of sock products, when replacing the loosening ring plate that also serves as a guide for the knitted fabric, depending on the knitting conditions of the sock, the knitting fabric guide cylinder is removed from the knitting machine cylinder of the sock knitting machine. This simplifies handling operations by making it easy to replace the locking ring plate without removing it.
It is an object of the present invention to provide a knitting fabric lowering guide device for a sock knitting machine that is designed to improve production efficiency.

[Structure of the idea]

(Means for Solving the Problems and Their Effects) In the present invention, a ring seat is formed at the upper opening of a knitted fabric guide cylinder fitted inside a knitting machine cylinder, and the knitted fabric is placed on this ring seat. A locking ring plate that also serves as a guide is detachably provided, and at least one or two or more protrusions projecting in the axial direction are formed on the inner peripheral edge of the locking ring plate. In order to prevent the strength of the knitted fabric lowering effect from occurring, to prevent the occurrence of uneven knitting and wrinkles, and to improve the quality of sock products, the above-mentioned loosening ring plate can be replaced according to the knitting conditions of the socks. When doing so, the loosening ring plate that also serves as guide for the knitted fabric can be easily replaced without removing the fabric guide cylinder from the knitting machine cylinder in the sock knitting machine, thereby simplifying handling operations and improving production efficiency. The aim is to improve the

(Example) Hereinafter, the present invention will be described with reference to an illustrated example.

In addition, the present invention will be described with the same reference numerals attached to the same constituent members as in the above-described specific example.

1 to 3, reference numeral 1 denotes a knitting machine cylinder in a sock knitting machine, and a knitting fabric guide cylinder 2 is fitted inside this knitting machine cylinder 1. Upper opening 2a of guide cylinder 2
is formed in a flat shape, and this upper opening 2
A ring seat 13 is formed in a. Further, on this ring seat 13, a locking ring plate 14 which also serves as a guide for the knitted fabric is provided so as to be detachable with each set screw 15. A plurality of (four in the figure) protrusions 14a are formed that protrude from each other.
A is designed to guide the drooping sock material W and pull it down.

Therefore, the suction fan 9 is driven in advance to generate suction force within the suction pipe 7. Next, when the sock fabric W hanging down from the knitting machine cylinder during the sock knitting process is guided to the upper opening 2a of the knitting fabric guide cylinder 2, at the same time, the loosening ring plate also serves as a guide for the knitted fabric. A plurality of protrusions 14a formed on the inner peripheral edge of the sock 14 guide the sock fabric W, thereby pulling the drooping sock fabric W downward.

Furthermore, as shown in FIG. 4, the sock fabric W guided to the knitted fabric guide cylinder 2 is
Due to the suction force of the suction fan 9 that is being driven,
The sock fabric W in the suction pipe 7 is pulled down into the suction pipe 7, and is stored in the fabric storage tank 8.

When the sock fabric W becomes full, the on-off valve 1
1 and temporarily blows air from the suction fan 9 up from the lower part 8a of the dough storage tank 8 through the communication pipe 12 and the connection pipe 10, thereby removing the dough stored in the dough storage tank 8. The sock fabric is taken out to the outside.

In addition, the above-mentioned loosening ring plate 14 which also serves as a guide for the knitted fabric of the present invention is applied to a sock knitting machine in which the knitting machine cylinder has four openings per rotation, such as in pantaste tsuking, for example. For example, when the knitting machine cylinder is used for one knitting machine per rotation, such as socks, the inner peripheral edge of the locking ring plate 14 is formed into one protrusion. In addition, depending on the knitting conditions of the socks, other anti-sagging ring plates 1 of the same shape and different size that also serve as guides for the knitted fabric may be installed.
